Dimensioning is carried out using diagram 1 (Sizes 0 – 2) or diagram 2 (Sizes 3 – 5) with “Torque M [Nm]” and “Misalignment [%]”:

1. Determining the “Torque M” coordinates:
   • Determine the maximum operating torque.
   • Multiply the operating torque by the values from the temperature factor table and service factor table (interpolate the interim values).
2. Determining the “Misalignment” coordinates:
   • Determine the individual shaft misalignments as a percentage, measured using the “permitted shaft misalignments” for the intended coupling size. Example for size 2: 0.2 mm axial displacement equals 25% of the permitted value 0.8 mm.
   • Add up the individual percentages. The sum total must be less than 100 percent.
3. Enter both determined coordinate values into the respective diagram. The point of intersection must lie below the characteristic curve of the intended coupling size.
4. If the point of intersection lies above the characteristic curve,
   • select a larger coupling,
   • reduce the shaft misalignments or
   • contact the manufacturer.
